• What is the cause and solution for SAP error message CNV_DMC_MC_EXCEPTION089 - Export parameters are not permitted for event-based rules ?

  The SAP error message CNV_DMC_MC_EXCEPTION089 indicates that there is an issue with the use of export parameters in event-based rules within the Data Migration Cockpit (DMC) or the Migration Object Model (MOM). This error typically arises when you attempt to define or use export parameters in a context where they are not allowed, particularly in event-based rules.
  Cause:
  
  Event-Based Rules: In SAP DMC, event-based rules are designed to trigger actions based on specific events during the data migration process. These rules do not support export parameters because they are intended to react to events rather than return values.
  Incorrect Rule Definition: If you have defined a rule that incorrectly includes export parameters, the system will throw this error when it tries to execute the rule.
  Configuration Issues: There may be a misconfiguration in the migration object or the rules defined for the data migration.
  
  Solution:
  
  Review Rule Definitions: Check the event-based rules you have defined in your migration object. Ensure that none of them include export parameters. If they do, you will need to remove these parameters.
  Use Import Parameters: If you need to pass values to the rules, consider using import parameters instead of export parameters. Import parameters can be used to provide necessary data to the rule without violating the constraints of event-based rules.
  Consult Documentation: Refer to the official SAP documentation for the Data Migration Cockpit and the Migration Object Model to understand the correct usage of parameters in event-based rules.
  Testing: After making the necessary changes, test the migration process again to ensure that the error is resolved.
